be furtherdescribed;-

. The customary cylinder heads, not shown, are mounted on the endsloftlhef cylinder in v'any of the various known ivays of attaching such heads to gas engine cylinders.

In the construction of Figs. l and 2, a piston 14.- is shown having three packing rings l5 in the-,periphery thereof, the construction of the piston and packing ringbeing old. i l

Iii the construction of Fig. 3 the cylinder sections 2a, 3a, and filling ring 4, and the iianges 5a, bolts 6a, and slotted flanges 7, 8, employed in securing the cylinder sections l 2a, 3, to the iilling ringi, are the same as lln the drawings, the numerals, 3

in Figs. 1 and 2, like parts having the same numerals with the letter a added thereto. In the construction of Fig. 3, however, the inner surfaces of one end of the cylinder sections 2'l and 3- are taper bored and a bushing 16 is inserted inthe end of each cylinder section 2. The bushings 1'6 taper on their outer surfaces andthe cylinder sections 21, 3, are bored to a corresponding taper, the outer ends of the bushings 16 having fianges 17 which are positioned within the recesses in the flanges 8, 7a, ofl the filling ring 4a and cylinder sections 2, 3a. The sectional filling ring 4a of Fig. 3 is the same .as that in Fig. 4, in the construction of Fig. 3 the filling ring preferably being made of the saine material as the bushings 16.

When the sectional cylinders'have been assembled and the engines are in readiness for operation the water used in the water jackets 10i-and 11, or 10a and 11a, cannot in any possible' manner leak into the engine cylinders, as each section of the cylinders has its own separate' and independent water jacket and water inlet and outlet openings.

When itis desired to inspect the piston 14 Ior 14a, and packing rings 15 or 15a, the sectional filling ring 4 or 4*l willbe removed,

, the cylinder sections 2 and 3 or 2a and 3 -the sectional filling ring is removed from` remaining in their erected position. After between the adjacent ends of the cylinder sections, the piston 14 or 14, when stopped in the middle of the length of the cylinder will be opposite the space ordinarily filled by the filling rings. The piston rings can then bereadily inspected and when required canrbe removed. and replaced Without the necessity, as has heretofore been the case, of removing the piston'from the cylinder. ln

this way the necessity of removing the cyl-v inder heads and disconnecting the piston rod from the engine cross head is avoided and rendered unnecessary. This is an important advantage which results in less time being required in making repairs and in maintaining the engines in operative condition.

Modifications in the construction and arrangement of the parts may be' made Without departing from my invention.

3.' A sectional gas, engine cylinder coin-- prising end sections, a segmental filling ring between the adjoining ends of the c linder sections, and bushings in the cylin er .sections, the outer surfaces of said bushings tapering andthe bushings being inserted 1n the cylinder from the a joining ends of the cylinder sections and engaging the ends 0f the filling ring to prevent movement of the bushings inthe cylinder.

4. A gas engine cylinder made in sections and havin a. sectional filling ring between the adjoining ends of the cylinder sections, a bushing removably secured in each cylinder section, said filling ring being arranged to hold the bushings in place in the cylinder sections when the engine cylinder is assembled.

5. A sectional gas engine cylinder comprising end sections, a segmental filling ring between the adjoining ends .of the cylinder sections, a bushing in each cylinder section, leach of said bushings having an annular fiange on one end thereof and the contactingfaces of the cylinder sections and ring hav` ing annular grooves to receive said flanges and prevent relative vmovement of the bushings in said cylinder.

In testimony whereof, I have hereunto set my hand.
